That is easy to explain... I can drop up to 4 mmol/l in 5 mins when I walk so your liver has to produce glucose constantly for your muscles unless you are in ketosis. It will maintain you at a reasonable level so you do not starve your muscles and become exhausted. That is why you ended up where you started.
Wow that is so interesting as for me my numbers will drop to 5 and stay there from wherever I am. Is it to do with amount of muscle/insulin resistance or exercise intensity. More likely a combination of all three and likely some other factorsI also find my twice daily walks raise my levels or keep them high (if they started high) for about an hour afterwards. This has been the case since I started testing. After about an hour back home they drop. It seems they help me in the long term but not the short term.
I'm not sure that is true Nicola. There will always be an affect whenever you do something whether that is positive or negative and will depend on intensity/duration/you current levels and digestion/.... A short non aerobic walk will likely not have a noticeable impact because you are using the glucogen stores within your muscles.Exercise doesn't always affect peoples blood sugars though, it does just depend on the person!!
Maybe, so but it never affected me back in school during PE it would change by like 0.6 or something nothing drastic..nobody is the same maybe it's different for a Type 2I'm not sure that is true Nicola.

Me too. Before lunch, 5.6. An hour and a half after lunch (chicken & ham salad) 5.6. Walk 1 mile to allotment, work moderately for just over an hour, walk home. 3 hours after lunch, 4.9.I've just done an experiment on me.
2hrs after lunch 6.5. (21g carbs, 38g fat, 37g protein)
Then spent an hour gardening. Lifting and carrying a lot of very heavy pots, pruning (bending), weeding (bending) and so forth
3hrs after lunch 6.5
It should have gone down on its own.
Interesting point here Andrew re the stored glucogen. Does that mean there will be some drop in bG post exercise as the muscles are replenished? Also, if it is a low level exercise but goes on for say 3 hours, would that trigger low bG for significant period (hrs) after the walk?I'm not sure that is true Nicola.

Yes I am luckier than you in that I do not need to worry about going hypo as I am a non-medicated T2I mostly use the ExCarbs structure for balancing this and found it pretty good.
Like you, I have used a lot of strips checking this.
- For light exercise for 2 or more hrs - cycling 10kph or walking - I will usually have a meal immediately prior.
- I reduce my fast acting insulin about 30% and snack hrly at my excarb rate (about 25-30gm/hr). That keeps me pretty even.
- But I do need to reduce Insulin or add carbs at the next meal (again about 30%) to make sure I don't go low.
- And if it is a long period of cycling 4 hrs or more, I need to watch for lows for 12 hrs
